WebChanges in ICP, mean arterial blood pressure (MABP), CPP, PaCO2, and jugular venous oxygen saturation (SjvO2) were recorded. With hyperventilation therapy, patients experienced a mean decrease in PaCO2 from 35 +/- 5 to 27 +/- 5 mm Hg and in ICP from 20 +/- 11 to 13 +/- 8 mm Hg (p < 0.001). WebHyperventilation is irregular breathing that occurs when the rate or tidal volume of breathing eliminates more carbon dioxide than the body can produce. [2] [3] [4] This leads to hypocapnia, a reduced concentration of carbon dioxide dissolved in the blood.
